Due to high pressure and temperature and the absence of air, the wood of the buried forest plants and trees slowly got converted into coal. The slow process by which the dead plants buried under the Earth have become coal is called carbonization. Since coal was formed from the remains of the plants, it is called a fossil fuel.
(a) The slow process of conversion of dead vegetation into coal is called ___. (b) Coal and petroleum are formed from the dead remains of organisms and are known as ___. (c) The black thick liquid with ___ smell is known as coal tar (d) During the processing of coal to get coke, coal tar and ___ are also obtained.
3. i) Coal ii) Coal iii) Liquified Petroleum Gas. 4. The slow process of conversion of dead vegetation 5. CNG is called clean fuel because: into coal is called Carbonisation. (i) It burns directly for burning. C + O2 CO2 (ii) It does not produce any pollution. So, A is wrong and R is correct.
As more soil deposited over them, they were compressed. The temperature also rose as they sank deeper and deeper. Under high pressure and high temperature, dead plants got slowly converted to coal. As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation. Question 4: Fill in the blanks.
Solution. Verified by Toppr. Dead remains of plants got buried under the earth millions of years ago. Due to intense heat and pressure inside the earth they got converted into coal. The process of conversion of dead remains of plants into coal is called carbonization.
A.) Coal is the one of the fuel used to cook food. B.) Process of conversion of dead vegetation into coal is called carbonisation. C.) CNG is used for power generation. D.) Coal gas is obtained during the processing of coal to get coke. E.) Petroleum gas is in liquid form. F.) The world's first oil well was drilled in Pennsylvania. 2.)
As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation. → Coal is one of the fuels used to cook food. It is also used in thermal power plants to produce electricity. and also used as a fuel in various industries.
CBSE Class 8 Chemistry Chapter 5 Coal and Petroleum Set 2. Q1: What advice did PCRA offer regarding fuel efficiency when driving? Q2: Identify the following: a) A fuel used in railway engines to produce steam. b) A process of conversion of dead vegetation into coal. c) A product used as a starting material in the production of explosives.
Best Answer. carbonisation Solution: Plants contain mainly carbon, which gets converted into coal. Hence, the slow process of conversion of dead vegetation into coal is called carbonisation. 3.
(a) The slow process of conversion of dead vegetation into coal is called ___. (b) Coal and petroleum are formed from the dead remains of organisms and are known as ___. (c) The black thick liquid with ___ smell is known as coal tar (d) During the processing of coal to get coke, coal tar and ___ are also obtained.
![Explain the process of carbonisation and how coal is formed? [5 MARKS]](/c4lb06x/84.jpg)
Under high pressure and high temperature, dead plants got slowly converted to coal. As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation. Since most of these substances were organic in nature, their decomposition led to large reserves of coal that we find today.
